To solve the system of equations, we can use the elimination method.Given the system of equations:
Step 1: Multiply the first equation by 2 to make the coefficients of
in both equations equal.
Step 2: Subtract the second equation from the first equation to eliminate
.
Since the resulting equation is true for all values of
and
, it means that the two equations are dependent and represent the same line. Therefore, there are infinitely many solutions to the system of equations.The correct choice is "Infinitely many solutions."
